SAW.

Specification of Letters Patent.

Patented Nov. 6, 1906.

To all whom it may concern:

Be it known that I, WILLIAM WALLACE OAKES, a citizen of the United States, residing at Seattle, in the county of King and State of Washin ton, have invented certain new and useful Improvements in Saws, of which the following is a specification, reference being had therein to the accompanying drawin s.

This invention relates to saws; and its object is to provide a saw of sim le form which will be easy to operate and eep in condition and which will make a cut sufficiently smooth to require no further manipulation is thereupon by a planer or the like.

The invention consists in the novel form and combination of the saw-teeth, as will be hereinafter described, and illustrated in the accompanying drawings, in which Fi ure 1 is an elevation of a portion of a sawlade embodying my invention. Fig. 2

is an edge or plan view of the same.

The teeth of the saw are arranged in groups, each group comprising two cuttin teeth A A and a gage and raker-tooth The cuttingteeth are severally provided with a single cutting edge e, which are all inclined in the same direction lengthwise of the saw, but filed so as to alternately slope 0 from and present the cutting edge upon opposite sides of the blade. The said cutting edges are inclined longitudinally, but little out of the horizontal, when the saw is held level, and consequently they sever the grain 3 5 of the wood being sawed by an incisive and not a chisel cut.

The intermediate teeth B are made rectangular, or nearly so, in longitudinal and cross sections and are of a depth from the 0 blade 0 slightly less than the extreme depth of the cutting-teeth for the purpose of providing a support to bear against the bottom of the sawerf and regulate the amount of cut made by each forward stroke of the saw.

5 This function is particularly advantageous in cutting the softer varieties of wood, as it prevents the saw-teeth bein buried too deeply and tearing the wood fi ers.

In operation with reciprocating or hand saws the cutting would always be done on the forward stroke of the saw, or in the direction indicated by the arrow in Fig. 1, and the saw would ordinarily be raised slightly on the reverse stroke.

It may be mentioned that by limiting the depth of the individual cuts, as is done by the introduction of the ga e-teeth, that the cut is not only made smoother, but the tendency to run or swerve from a plane is re-- duced to a minimum, and the cutting-teeth which are formed and arranged accordin to this invention will require no setting ot er than is made b the side pressure received from the file in s arpening.

Having described my invention, What I claim as new, and desire to secure by Letters Patent, is

A straight-edge saw having cutting-teeth arranged in groups of two teeth, both the front and rear edges of each tooth being at right angles to the edge of the saw, the teeth of each roup being beveled at reverse angles one to the other and reversely set, the beveled surfaces of said teeth being at an an 1e to the straight edge of the saw longitudina ly of said edge and the sharp edges of all the cutting-teeth being inclined in the same direction, the saw having gage-teeth alternating with the groups of cutting-teeth, the front and rear ed es of said gage-teeth being disposed at ri ht angles to the blade of the saw and havin lunt edges parallel with the edges of the bla e.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM WALLACE OAKES.
